pokerstars satalites

Was just playing, and there was 5 times a headsup allin overpair vs underpair. And all 5 times the turn turned the underpair a set. Is this rigged?

I won this sat because I turned a set vs an overpair so im not whining because I lost
but it just happens too often, when I was allin I just said to a friend sitting here, watch the turn will give me a set.
